Design on detection system for laser fuze using pseudorandom code

Laser proximity fuzes adopted on semiconductor laser have been widely used in various kinds of guided missiles and routine ammunitions. An approach to pulsed laser fuze based on pseudorandom code is designed. Based on the principle of laser fuze using pseudorandom code, the system is divided into emitting module, receiving module, optical system and information processing module. The different modules are analyzed, and principles for selecting the parameters of the modules are given. The theoretic foundation is provided for scientifically designing pulsed laser fuze of pseudorandom code.
